Abstract

An array sensor was designed to use polyvinylidene fluoride and the sensor could measure the acoustic radiation modes amplitude of the laminated composite plate. Using the designed theory of acoustic radiation modal sensor in ref.[1], the measurement accuracy factors of the sensor of acoustic radiation modes were presented, such as sensor paste location and direction. Natural frequency, the first order acoustic radiation mode amplitude and the acoustic radiation power of the laminated composite plate were tested by the sensor. And experimental results and the numerical simulation are presented.
